NEW QUESTION # 165
You are developing an asynchronous, decoupled billing microservice that consumes payment messages from an Oracle Cloud Infrastructure (OCI) Queue. You notice that some corrupted payment payloads are causing the consumer application to fail and restart repeatedly, leaving the messages unprocessed and blocking the queue. To isolate these toxic messages, you want to redirect them to a Dead Letter Queue (DLQ) after 5 failed delivery attempts.
Which TWO configuration steps or characteristics must you apply to implement this solution?
Answer: A,B
Explanation:
The supplied Word answer key requires correction here. Current Oracle Queue documentation explicitly states that adead letter queue is automatically created when a queue is created. Therefore, option C is correct and option B is not. Oracle also provides the Maximum delivery attempts setting, which controls how many unsuccessful deliveries can occur before a problematic message is transferred to the DLQ. Setting that value to 5 implements the requested retry threshold. No separately provisioned target queue is required, consumer groups are optional and unrelated to enabling DLQ functionality, and administrators do not create an IAM policy authorizing a source queue resource to write to its automatically associated DLQ. Consequently, the verified current answer isA, C, not the Word file ' s A, B.
NEW QUESTION # 166
Your company requires strict compartment isolation for an event-driven automation framework. You have deployed an Oracle Functions function inside a secure compartment named SecOps-Fn-Compartment. An OCI Events rule has been configured in a separate compartment named App-Resources-Compartment to capture critical resource state changes. Which configuration approach is required to allow the OCI Events service to successfully invoke your function?
Answer: D
Explanation:
OCI Events invokes configured action resources as a managed service rather than by assuming the identity of the human user who created the rule. Oracle ' s Events material documents the service principal cloudEvents and the policy pattern allowing that service to use functions-family. Scoping that permission to the compartment containing the target Function provides the required compartment isolation. A dynamic group is inappropriate because an Events rule is not a Compute instance or workload principal. Granting permissions to oraclefunctions reverses the invocation relationship, while granting a user group broad function- management rights does not authorize the Events runtime itself. Current Oracle documentation additionally represents cross-tenancy delivery using an eventrule principal and FN_INVOCATION; within the source scenario, B is the intended service authorization model.
NEW QUESTION # 167
From a DevOps process standpoint, it is a good practice to keep changes to an application under version control. Which of the following allows changes to a Docker image to be stored in a version control system?
Answer: D
Explanation:
The option that allows changes to a Docker image to be stored in a version control system is: docker commit The docker commit command is used to create a new image from a container ' s changes. It takes a running container as input, captures the changes made to it, and creates a new image with those changes. This new image can then be tagged and pushed to a registry, or saved locally. By using docker commit, you can effectively capture the changes made to a container as a new image and store it in a version control system along with the Dockerfile and other project files. This allows for reproducibility and traceability of changes to the Docker image over time.
NEW QUESTION # 168
Who is responsible for patching, upgrading, and maintaining the worker nodes in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE)? (Choose the best answer.)
Answer: C
Explanation:
The user is responsible for patching, upgrading, and maintaining the worker nodes in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). In OKE, the user has control over the worker nodes, which are the compute instances that run the Kubernetes worker components. As the user, you are responsible for managing and maintaining these worker nodes, including tasks such as patching the underlying operating system, upgrading Kubernetes versions, and performing any necessary maintenance activities. While Oracle provides the underlying infrastructure and support services, including managing the control plane and ensuring the availability of the OKE service, the responsibility for managing the worker nodes lies with the user. This allows you to have control and flexibility in managing your Kubernetes environment according to your specific needs and requirements.
NEW QUESTION # 169
What is the maximum allowable size for a secret bundle stored in the Oracle Cloud Infrastructure (OCI) Vault service?
Answer: D
Explanation:
Oracle Secret Management documentation explicitly specifies that themaximum allowable size for a secret bundle is 25 KB. This limit applies when creating a secret or creating a new version of an existing secret.
When using the OCI Console, administrators can enter plain-text secret contents and the Console performs the required Base64 encoding. When communicating directly with the service through supported APIs or CLI operations, secret contents must be supplied in the required encoded form. Secrets are intended for security- sensitive values such as passwords, API tokens, certificates, and configuration credentials rather than arbitrary large files. Payloads exceeding the supported secret-bundle size should therefore be redesigned, divided appropriately, or stored using a service suited to larger objects. Consequently, B is the verified Oracle limit.
